Description
Technical field
The present invention relates to the measuring method of a kind of Nicotiana tabacum L. physical characteristic, particularly relate to a kind of measurement expanded cabo slice thickness
Method.
Background technology
Cabo is the important component part of Nicotiana tabacum L., accounts for leaf and weighs 25%～30%.In recent years, increasing research shows,
Process, through modes such as hot and humid expansion, microwave treatment, the expanded cabo miscellaneous QI that obtains, xylon gas significantly reduces, and suction quality carries
Rise；Meanwhile, the cabo Filling power after expansion process is high, has weight in terms of improving cigarette structure, reducing Medicated cigarette cost and fall Jiao
Act on.Currently, the modes such as hot and humid expansion, microwave expansion and collaborative expansion technique are used to obtain expanded cabo, Jin Erjie
Plying shape moulding process prepares expanded cut stem, is just becoming the main process that expansion stem is applied in Medicated cigarette.Wherein, by cutting
Sheet machine obtains high-quality expansion stem stalk sheet, is the core of the thread moulding process of expansion stem.
In expanded cabo slice processing processing procedure, expansion stem slice thickness is an important physical index, impact
The following process of expansion stem stalk sheet, affect yield and the quality of the thread product of expansion stem the most to a certain extent.Therefore, essence
Really measure expansion stem slice thickness, be one of core Con trolling index in expansion stem thread forming processes technique.
Through various the expansion process expansion stem obtained and the conventional cabo originally used in physical aspect and interior tissue
The aspect such as density have great difference, therefore differ greatly in processability.The usual volume of expanded cabo increases several times, wide
Degree and thickness dramatically increase, and interior tissue becomes cavity structure, and after humidifying charging processes, quality is soft, and elastic big, this makes swollen
After the sliced process of swollen cabo, thickness there will be " resilience " phenomenon, often lead to expanded cabo chopper and slicer digital display slice thickness with
There is larger difference in actual measured value, is difficult in process of production effectively control product homogeneity, after affecting expansion stem stalk sheet
Continuous processing.
At present, domestic tobacco business is interior and is formed without the expanded cabo slice thickness measuring method imitated.If producing
Journey can not accurately be understood expansion stem slice thickness, it will cause the expansion stem stem unstable product quality finally given,
Rate and uniformity are relatively low.
Summary of the invention
For accurately understanding expansion stem slice thickness, the present invention provides a kind of method measuring expanded cabo slice thickness, real
Now expanded cabo slice thickness effectively detected and control.
In order to realize above-mentioned purpose, the present invention is achieved through the following technical solutions: a kind of measurement expanded cabo slice thick
The method of degree, through following each step:
(1) choose hot strength be 14～20MPa, elongation at break be the material of 280～400%, by the shapes and sizes of material
Make similar to expanded cabo, obtain material to be detected；This material hardness is moderate, elastic relatively low；
(2) between 0.08～0.8mm, the slice thickness of chopper and slicer is adjusted as desired, by the material to be detected of step (1)
Mixing with expanded cabo, making material to be detected account for, mixed population is long-pending 5～10%, and mixture is invested in properly functioning section
Equipment is cut into slices, obtains section to be measured；
(3) in the section to be measured of step (2) gained, randomly select the section to be measured of 10 materials to be detected, and by its stacked in multi-layers
Become stereo block, measure the thickness of the left part of stereo block, middle part, right part respectively, be labeled as A successivelyLeft、AIn、ARight, repeated measure n times,
N≥5；
(4) single value d of the slice thickness of expanded cabo is calculated as follows:
dN=(AN is left+ AIn N+ AN is right)/30
In formula: the single measurements of the slice thickness of d expanded cabo, unit is mm；
The left part of A stereo block, middle part, the thickness of right part, unit is mm.
The pendulous frequency of N stereo block thickness；
(5) the average slice thickness of expanded cabo is calculated as follows:
D=(d1+d2+d3+···+ dN)/N
In formula: the average slice thickness of D expanded cabo, unit is mm.
The material of described step (1) is the materials such as PP, EVA, PE or PVC.
Preferred as safety, material uses PP material.
Being made by material of described step (1) is identical with the size of expanded cabo, is to use conventional injection mo(u)lding or extruding
Moulding process processing obtains.
The invention have the advantages that and present invention achieves the detection means unified to cutting rear expanded cabo, it is achieved that be right
Expanded cabo slice thickness effectively detects and controls.The present invention detects for slice thickness, and testing result degree of accuracy is high, reliability
By force.Operational approach is simple, workable；Calibration to chopper and slicer plays directiveness effect.And can further appreciate that swollen
Swollen stalk slice thickness, makes the expansion stem stem constant product quality finally given, yield and uniformity high.
